Changing samples on Drumkit

I wanted to change some of the snare samples with the kits “with Bass” I have downloaded from the forum. When a change the sample it saves ok, it also shows in folder…
but beatbuddy doesnt show the new kit in the drop down menu as available kits…please assist…

Update: I notice when I save it, then go back in…There is no sound on the samples I have changed.

No need to double-post the same topic. Thanks
